We will now focus briefly on the importance of vaccines. Vaccines keep us from catching dangerous infections and help us avoid the need for medical treatments like antimicrobials.

How Vaccines work

Vaccines help develop immunity by imitating dangerous microbes that our bodies may be exposed to.

  • Once the immune system is exposed to the dead or disabled microbes in vaccine, the body will remember how to fight that disease in the future.
  • Sometimes vaccines can cause minor symptoms, such as fever. Such minor symptoms are normal and should be expected as the body builds immunity.
  • To build up immunity you may need more than one dose

Vaccines can be given in different ways, by injection, in drops or nasally.
